METALLIC PACKING.

Application filed June 23,

My invention relates to improvement in metallic packing composition to be employed particularly in connection with reciprocating piston re s n is an object of the invention to provide a packing composition which will resist heat and wear and which may be con'iprcssed to expand the It is another object of provide a packing of durable lubricating,

contact with the rod 2, thus making a fluid tight joint allowing the reciprocation of the red but adapted to prevent leaking of steam past the packing. The central core being made oi rubber will allow the distortion of the packing ring within the stufling box under pressure in such manner as to make a practically tight joint. The babbitt mixed with the graphite and oil will withstand the lubricant further than the material of which it is made and will last for long periods of time. A. parking made up of this material is 'found to be particularly efficient for the purpose stated and its advantages will be apparent to one skilled in the art without further description.

that I claim as new and desire to protect by Letters Patent is:

1. A metallic piston packing comprising a cylindrical core of rubber, a surrounding layer made up of a mixture of babbitt, graphite and oil, and an outer protecting cover of fabric.

2. A piston packing comprising a core of rubber, a surrounding layer of graphite. oil, and babbitt, and an outer protecting cover of flexible material.

In testimony whereof, I hereunto aliix my signature this the 19th day of June.
